背景:这项研究比较了基于硅酸钙的根管封闭剂的无意根尖挤压后闭塞后疼痛的强度(EndoSequenceBCSealer[BrasselerUSA,萨凡纳,GA]和Bio-C密封剂[Angelus,Londrina,PR,巴西])用树脂基密封剂(AHPlus;DentsplySirona,约克,PA).
方法:招募了330例无症状的不可逆性牙髓炎的磨牙根管治疗患者。使用WaveOneGold仪器(DentsplySirona)以冠向下技术制备根管,并用2%氯己定凝胶和盐溶液冲洗。接下来,根据使用的根管封闭剂将患者随机分为3组(n=110):AHPlus,BCSealer,和Bio-CSealer.然后用垂直压实技术完成根管充填。在6-时,使用0-10的视觉描述量表评估了出现密封剂意外挤出的患者(n=13/组)的闭塞后疼痛体验,12-,24-,治疗后间隔48小时和1周。使用方差重复测量的混合分析来评估结果(α=0.05)。
结果:所有密封剂的挤出速率相似(~12%)。评价的根管封闭剂之间的闭塞后疼痛结果没有显着差异(P>0.05)。然而,在12小时的时间间隔之后,AHPlus(P=.04073)和Bio-CSealer(P=.04327)显示疼痛显着减轻,而BCSealer没有显示疼痛强度的差异,即使在评估的最长时间为1周(P>.05)。
结论:与具有低强度疼痛的树脂基密封剂相比,硅酸钙基根管密封剂的意外根尖挤压的发生表现出相似的术后疼痛结果。
BACKGROUND: This study compared the intensity of postobturation pain after unintentional apical extrusion of calcium silicate-based root canal sealers (EndoSequence BC Sealer [Brasseler USA, Savannah, GA] and Bio-C Sealer [Angelus, Londrina, PR, Brazil]) with a resin-based sealer (AH Plus; Dentsply Sirona, York, PA).
METHODS: A total of 330 patients referred for root canal treatment on molar teeth with asymptomatic irreversible pulpitis were recruited. Root canals were prepared using WaveOne Gold instruments (Dentsply Sirona) in a crown-down technique and irrigated with 2% chlorhexidine gel and saline solution. Next, patients were randomly distributed into 3 groups according to the root canal sealer used (n = 110): AH Plus, BC Sealer, and Bio-C Sealer. Root canal filling was then accomplished with a vertical compaction technique. Patients presenting with an unintentional extrusion of sealers (n = 13/group) were assessed for postobturation pain experience using a visual descriptor scale ranging from 0-10 at 6-, 12-, 24-, and 48-hour and 1-week intervals after treatment. Mixed analysis of variance repeated measures were used to assess the results (α = 0.05).
RESULTS: The extrusion rate was similar for all sealers (~12%). There was no significant difference in the postobturation pain results between the root canal sealers evaluated (P > .05). However, after the time interval of 12 hours, AH Plus (P = .04073) and Bio-C Sealer (P = .04327) demonstrated a significant reduction in pain, whereas BC Sealer did not show differences in pain intensity, even in the maximum period evaluated of 1 week (P > .05).
CONCLUSIONS: The occurrence of unintentional apical extrusion of calcium silicate-based root canal sealers presents similar postoperative pain results compared with resin-based sealers with low-intensity pain.
